摘要
本文制备了一种由高性能水泥基材料和保温材料复合组成的UHPC保温装饰一体板,其中胶凝材料饰面层采用白色硅酸盐水泥、白硅灰、偏高岭土的三元胶凝组成体系,结构层采用普通硅酸盐水泥、硅灰、粉煤灰的三元胶凝组成体系,钢纤维选用端钩型镀铜微纤维,掺量为2.0%。制备的性能优良的UHPC保温装饰一体板具有坍落扩展度为860~910 mm的优良工作性能,28天抗压强度和抗折强度分别为126~138 MPa和17~23 MPa。在此基础上,总结了UHPC保温装饰一体板的安装和施工工法,分析了其技术特性和在装配式建筑中的应用案例。本研究表明,UHPC保温装饰一体板强度高、重量轻、保温性能好,且施工方式简单,应用范围广,具有良好的应用前景。
In this paper, a kind of UHPC insulation decoration integrated board made of high-performance cement-based materials and insulation materials was prepared. The cementing material finishing layer was composed of white Portland cement, white silica ash and metakaolin, and the structural layer was composed of ordinary Portland cement, silica ash and fly ash. The structure layer is composed of ordinary Portland cement, silica fume and fly ash. The end hook type copper-plated microfiber was selected for steel fiber, and the content was 2.0%. The prepared UHPC insulation decoration integrated board with excellent performance has excellent working performance of slump expansion of 860~910 mm, 28-day compressive strength and flexural strength of 126~138 MPa and 17~23 MPa, respectively. On this basis, the installation and construction methods of UHPC insulation decoration integrated board are summarized, and its technical characteristics and application cases in prefabricated buildings are analyzed. The research shows that UHPC insulation decoration integrated board has high strength, light weight, good insulation performance, simple construction method and wide application range, and has a good application prospect.
